Expert Mold Remediation

MoldMold is one of the biggest worries of a homeowner by virtue of the fact that it can spread quickly. Mold remediation is not a task an untrained professional should attempt. It takes many hours to learn and develop the appropriate procedures to remediate mold without causing further contamination in the home

Zion Restoration has over ten years of experience in mold remediation and is certified through an independent agency, IICRC at www.IICRC.org. Zion restoration uses IICRC Standards, Center for Disease Control (www.CDC.org/mold) and Environmental Protection Agency (www.EPA.org) standards when providing mold remediation services.

How does mold grow?

Household Mold needs 3 things to grow:
  • A food source (such as wood, paper or drywall)
  • A water source (such as a dripping faucet, leaky basement or moisturized attic)
  • The right temperature (72 degrees Fahrenheit or more)

Is it “killer mold”, “black mold” or Stachybotrys chartarummold?

The type of mold you have in your home can only be determined by a mold sampling test performed by an Industrial Hygienist.

What do I do?

  • Get an air quality and sample test in your home by a licensed Industrial Hygienist who can write a prescription for a certified mold remediator or contractor to perform a mold remediation.
  • Close off the area of the home to keep the contamination from spreading to the other areas of home.

Mold Prevention as per Center for Disease Control



The key to prevention in the design and operation of buildings is to limit water and nutrients. The two basic methods for accomplishing that are keeping moisture-sensitive materials dry and, when wetting is likely or unavoidable, using materials that offer a poor substrate for growth. Specifically, design and maintenance strategies must be implemented to manage:

  • Rainwater and groundwater, preventing liquid-water entry and accidental humidification of buildings.
  • The distribution, use, and disposal of drinking, process, and wash water, making equipment and associated utilities easily accessible for maintenance and repair.
  • Water vapor and surface temperatures to avoid accidental condensation.
  • The wetting and drying of materials in the building and of soil in crawlspaces during construction.

Little scientific information on the efficacy and impact of prevention strategies is available. Moreover, little of the practical knowledge acquired and applied by design, construction, and maintenance professionals has been subject to thorough validation. Since the 1993 New York City Department of Health (NYCDOH) document (Assessment and remediation of Stachybotrys Atra in Indoor Environments) was produced, a number of other guidance documents have been written, including:

The seven documents were each developed by a group of people with identified expertise in building and engineering issues, mycology, and occupant health assessment. Topics are not uniformly covered by the documents. The documents agree that:

  • Mold should not be allowed to colonize materials and furnishings in buildings.
  • The underlying moisture condition supporting mold growth should be identified and eliminated.
    • The International Society of Indoor Air Quality and Climate (ISIAQ) and ACGIH guidelines discuss moisture dynamics, identifying problematic moisture or remediating moisture problems.
    • U.S. EPA guidelines contain specific recommendations for a variety of water-damaged materials.
  • The best way to remediate problematic mold growth is to remove it from materials that can be effectively cleaned and to discard materials that cannot be cleaned or are physically damaged beyond use.
  • Occupants and workers must be protected from dampness-related contaminants during remediation.
    • All the guidelines agree that some mold situations present a small enough exposure potential that cleanup does not require specific containment or worker protection but that other situations warrant full containment, air-pressure management, and full worker protection. Situations between those extremes need intermediate levels of care. Guidance for selecting appropriate containment and worker protection for different situations lacks clarity within and between documents.
  • Heating, Ventilation, and Air Condition (HVAC) systems are special cases. The documents disagree on how to respond to contamination in HVAC systems.
  • The documents are divided on the use of disinfectants.

“Zion’s many crew members immediately acted to recover whatever they could and to stop any further damage.  All of their workers, especially Glenn, Pete, Terry and Kevin were respectful of us and our belongings, and made the unfortunate situation easier.  They were always polite, trustworthy, and honest and from the beginning, we felt they were definitely the company that could do the job.”
